Hi all,
MathMod release candidates 1.0 are available for download from:
https://sourceforge.net/projects/mathmod/files/MathMod-1.0/Release%20Candidate/
The release candidate contains all features that should be in the MathMod 1.0 version but I still have to fix some minor issue in the code.

|
|
After installing MathMod-1.0-RC2(WIN64).exe under Windows 7 Pro SP1 64 Bit and trying to start it, I get this error message:
---------------------------
Microsoft Visual C++ Runtime Library
---------------------------
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
---------------------------
OK
---------------------------
Any idea who to bring it run?
Or can you please publish an additional 32 bit version too? |

Hi,
The third release candidate MathMod-1.0-RC3 is available to correct two tickets shown at:
https://sourceforge.net/p/mathmod/tickets/14/ and
https://sourceforge.net/p/mathmod/tickets/15/
@inode
Can you please try to desinstall MathMod firt and reinstall the last release RC3? there is also a a ziped package of the RC3 that you can try...I had the same error message before including a new dll in the RC2 package and it looks like after installing the RC2 in your machine, an old dll from the MathMod-1.0-Beta version wasn't updated!
I'll upload a 32 Bit version later

Hi Gerd,
I discovered a memory leak in the RC2 and RC3 version that is probably the cause of the crash you experiencing, because it happens if you don't have enought RAM on your machine. I'll fix it later
Ticket:

|
|
Hi Abderrahman
As you told me I was uninstalling MathMod to prevent the starting bug.
Okay, now I am able to start and test MathMod RC4...
Some notes about uninstalling:
- If MathMod is still in action, uninstalling will not be able to delete all files.
- Deinstallion process kills also modified / extented json scripts

Hi,
To prevent loosing your data, you can specify a new working folder other than the installation folder. For this, you have specify the working folder in the command line/link that lunch MathMod as an argument:
| Code: | | MathMod.exe WorkingFolderName |
or, change the "Target" property of the link in your Desktop from:
| Code: | | "C:\Program Files (x86)\MathMod\MathMod.exe" |
to something like:
| Code: | | "C:\Program Files (x86)\MathMod\MathMod.exe" "C:\Users\Nextstep\Desktop\NewWorkingDir" |
Also, you can give MathMod a .k3ds file that contain a mix of isosurfaces and parametric surfaces and it will generate a .js file

hello
thanks for your new version.
In fact version x64 of RC4, is a 32bit version, because the installation path is in
programme'X86°
And the prog cannot have more 3G of memories.
(is just to say)
cheers

Hi Denisc,
Of course you can go up of 3GB 
I'll not recommend it but here is how:
You have to edit manually the file mathmodconfig.js and set the first tree fields to, for example :
| Code: | {
"IsoParam": {
"MaxGrid": 400,
"MaxPt": 50,
"MaxTri": 80
},
....
} |
I have 8GB of RAM and MathMod can use something like 6.7GB with this configuration.
To test this:
1) Lunch MathMod after making the changes in the config file
2) click on the "MengerSpongeSubdivision" example.
3) click on the "Grid/colors" tabulation and uncheck the "XYZ" button
4) pull the "iso grid" bar to it's maximum value (400)
5) check the "XYZ" button and wait...
after a while, you should have something like the screenshot.
Of course if you have more than 8GB of RAM, you can push the specs a little bit further

THANKS for your solution.
it is possible to build fractales with new version of mathmod.
(to used complex numbers in fact with reel and imaginary)? |

Hi ,
@denisc: The Sierpinski fractal is feasible but the 3D Mandelbrot should be a little bit more complicated to represent as a 3D isosurface. The big problem with the fractal definitions is that they use recursive functions and MathMod doesn't support such functions. Complex numbers are great but Mathmod doesn`t support them (for the moment )
@ who8mypnuts : you're welcome

Hi all,
The next release will allow setting the Parametric maximum grid in the config file.
As for the isosurface representation, the parametric surfaces resolution will be limited only by the amount of the RAM in your machine.
K3DSurf was limited to 100x100 while MathMod will be virtually unlimited...
You better, however, have a good graphics GPU that can handle hight resolution models like this Shel with 64.6 Millions polygons.
Stay tuned
